[0045] Specifically, this labeling device is arranged at the last link of the detection equipment on the production line to function as an NG mark.

Specifically, the first driving source 51 is a servo motor, and the second driving source 52 is a magnetic powder motor; when the labeling device operates, the first driving source 51 and the second driving source 52 drive the winding shaft 3, the driving shaft and the unwinding shaft 2 to rotate respectively, but the rotation speeds of the first driving source 51 and the second driving source 52 are different, so that a resistance can be formed to tension the label tape.

[0051] Further, the separating knife 6 is of a plate-like structure, one side of the separating knife 6 is a plane, and the other side is an inclined plane. The pressing roller 7 is arranged on the side close to the plane, and the end with a thinner thickness of the separating knife 6 is its working end, and the end with a thicker thickness of the separating knife 6 is its connecting end.

[0053] Further, the driven shaft 42 can be adjusted in position within a certain range to approach or move away from the driving shaft 41, so as to realize the adjustment of the acting force of the power shaft assembly 4 on the label tape and ensure the driving effect of the power shaft assembly 4 on the label tape.

A straight groove extending along its length direction is formed in the connecting plate; a clamping block is arranged on the substrate 1, and a connecting rod perpendicular to the substrate is connected to the clamping block. One end of the connecting rod far away from the substrate 1 is inserted into the straight groove through a flat structure and fastened by screwing a bolt. In this way, by rotating the connecting rod and adjusting the position of the connecting rod in the straight groove, the position of the pressing roller 7 can be adjusted, so as to ensure the use effect of the pressing roller 7.

[0055] Further, a displacement stage is arranged on the substrate 1, and the fiber optic sensor 8 is installed on the displacement stage. The displacement stage can adopt a manual XY-axis displacement stage. Through the displacement stage, the position of the fiber optic sensor 8 can be precisely adjusted to ensure the most suitable distance between the fiber optic sensor 8 and the label tape passing through its detection end, so that the fiber optic sensor 8 has a better use effect. Specifically, the working principle of the fiber optic sensor 8 is to sense the change of high and low levels. When the fiber optic sensor 8 recognizes the label on the label tape, it is at a high level. When the fiber optic sensor 8 recognizes the blank tape between two adjacent labels on the label tape, it is at a low level. When the high level changes to the low level, the label tape stops moving.

[0056] Further, the pressing roller 7 is a foam roller. During the movement of the label tape, the foam roller will also rotate and play a role in flattening the label.
